Overview

Package periph is a peripheral I/O library.

Is it now superseded by https://periph.io/x/conn/v3 (or later), https://periph.io/x/host/v3 (or later), https://periph.io/x/devices/v3 (or later) and https://periph.io/x/cmd.

See https://periph.io/news/2020/a_new_start/ for more details.

Example
package main

import (
	"fmt"
	"log"

	"periph.io/x/periph/host"
)

func main() {
	// host.Init() registers all the periph-provided host driver automatically,
	// so it is preferable to use than periph.Init().
	//
	// You can also use periph.io/x/extra/hostextra.Init() for additional drivers
	// that depends on cgo and/or third party packages.
	state, err := host.Init()
	if err != nil {
		log.Fatalf("failed to initialize periph: %v", err)
	}

	// Prints the loaded driver.
	fmt.Printf("Using drivers:\n")
	for _, driver := range state.Loaded {
		fmt.Printf("- %s\n", driver)
	}

	// Prints the driver that were skipped as irrelevant on the platform.
	fmt.Printf("Drivers skipped:\n")
	for _, failure := range state.Skipped {
		fmt.Printf("- %s: %s\n", failure.D, failure.Err)
	}

	// Having drivers failing to load may not require process termination. It
	// is possible to continue to run in partial failure mode.
	fmt.Printf("Drivers failed to load:\n")
	for _, failure := range state.Failed {
		fmt.Printf("- %s: %v\n", failure.D, failure.Err)
	}

	// Use pins, buses, devices, etc.
}

Functions

func MustRegister

func MustRegister(d Driver)

MustRegister calls Register() and panics if registration fails.

This is the function to call in a driver's package init() function.

func Register

func Register(d Driver) error

Register registers a driver to be initialized automatically on Init().

The d.String() value must be unique across all registered drivers.

It is an error to call Register() after Init() was called.

Types

type Driver

type Driver interface {
	// String returns the name of the driver, as to be presented to the user.
	//
	// It must be unique in the list of registered drivers.
	String() string
	// Prerequisites returns a list of drivers that must be successfully loaded
	// first before attempting to load this driver.
	//
	// A driver listing a prerequisite not registered is a fatal failure at
	// initialization time.
	Prerequisites() []string
	// After returns a list of drivers that must be loaded first before
	// attempting to load this driver.
	//
	// Unlike Prerequisites(), this driver will still be attempted even if the
	// listed driver is missing or failed to load.
	//
	// This permits serialization without hard requirement.
	After() []string
	// Init initializes the driver.
	//
	// A driver may enter one of the three following state: loaded successfully,
	// was skipped as irrelevant on this host, failed to load.
	//
	// On success, it must return true, nil.
	//
	// When irrelevant (skipped), it must return false, errors.New(<reason>).
	//
	// On failure, it must return true, errors.New(<reason>). The failure must
	// state why it failed, for example an expected OS provided driver couldn't
	// be opened, e.g. /dev/gpiomem on Raspbian.
	Init() (bool, error)
}

Driver is an implementation for a protocol.

type DriverFailure

type DriverFailure struct {
	D   Driver
	Err error
}

DriverFailure is a driver that wasn't loaded, either because it was skipped or because it failed to load.

func (DriverFailure) String

func (d DriverFailure) String() string

type State

type State struct {
	Loaded  []Driver
	Skipped []DriverFailure
	Failed  []DriverFailure
}

State is the state of loaded device drivers.

Each list is sorted by the driver name.

func Init

func Init() (*State, error)

Init initialises all the relevant drivers.

Drivers are started concurrently.

It is safe to call this function multiple times, the previous state is returned on later calls.

Users will want to use host.Init(), which guarantees a baseline of included host drivers.
